Geospatial technology and geo computation
Budget: €30 – €250 EUR
Following tasks
Please use labelled diagrams (where relevant) to support all answers
1. Earth Observation (10 marks)
a) Download and process Sentinel-2 sub-scene
Note: This practical was detailed in Lecture-1 (17th April 2023) – see ‘Lecture-1_EO_Practical.pdf’
Practical: Search, Download, process & export Sentinel-2 image sub-set (roughly 10km*10km in size) as per instructions in “Lecture-1_EO_Practical.pdf’”- in first Lecture
• The Sentinel-2 colour image composite should comprise 3 X bands that match (as closely as possible) typical Red, Green, Blue composite camera images.
• Try and centre the 10km*10km Sentinel-2 sub-image, centred (approximately) over the town or close to the area where you live
• Cut’n’paste screen-grabs of each step – including final image output and provide a description (3 page max) of the main steps involved including; (i) search, retrieval & download and (ii) processing & (iii) final display/visualisation – apply a ‘linear stretch’ to improve brightness/contrast of the image if required.
Answer the following (use diagrams where relevant)
b) Define Earth Observation and provide 2 X application examples(EO)
c) What is an NDVI, how is it computed, what does it tell us.
d) Define and explain the difference between Clustering and Classification, provide at least 2 X
examples of each
2. Geodesy, Mapping, Photogrammetry & Drones
(a) Describe and detail (using a diagram) Earth Surface, Geoid and Ellipsoid
(b) Why do we need Map Projections and name 4 X map projection transformation properties that may need to be distorted
(c) Define and provide details for DSM & DEM
(d) What is the practical application of KLV in Aerial Full Motion Video
(e) Details and describe the 3 X main categories governing Drone Operations in Europe/Ireland
CS431 : Geospatial Science & Computation Assessment Exercise
3. Geospatial Web Architectures & Open Source Technologies
(a) Provide an overview of Geospatial Web Architecture, clearly identifying key Open Source Technologies & associated standards
(b) Provide an example of a Geospatial Web UI/UX – what do you think is important to consider when designing UI/UX for Geospatial Web applications
